For many years I rode a Navi from Medion. It was good, but outdated, the maps slowly. That's why I was looking for a Navi that offers a lifetime free map updates. This Garmin Nuvi 66LMT Premium Traffic navigation device I've found it. As usual with Amazon, the device was delivered quickly. After reading the Quick Start Guide I reported to Garmin to aufzuspielen to the latest update. That worked out great and everything has been updated in about 1 hour and thirty minutes. Thus, the navi was up to date. The service is quick and the screen, thanks to its size of 6 inches, is the itinerary well available. Bright and clean the Navi shows you the way. The announcement is accurate and comes relatively early naming the street. At least with my driving style, it is sufficient. What is wrong, is my street. Although several years 30 Km / h, the Navi shows the wrong speed. But this was just the old Navi. The technical data are, of course, to find out from Garmin. I would buy this again Navi. It has convinced me.
